Subject: [PATCH v2 3/4] ARM: dts: aspeed: bletchley: Add second source PCA9532 LED controllers
Date: Wed, 29 Jul 2026 19:43:11 +0800 [thread overview]
Message-ID: <20260729114312.3947300-4-chou.cosmo@gmail.com> (raw)
In-Reply-To: <20260729114312.3947300-1-chou.cosmo@gmail.com>
Add alternative PCA9532 LED controllers at address 0x66 to support boards
populated with the PCA9532 instead of the primary PCA9552 at 0x67.
